'Application .my zo, 1932, serial No. 623,517 sclaims. (0134-26) IIL This invention relates` to hair driers and more particularly to a novel multiple hair drier.' Among the objects of the invention are:

Provision of a piuranty of hair drying'1 units mountedon a single stand. Generation of heat and velocity of 'drying medium (such as air) for all units within the stand. Provision for heating the drying medium'before same is given velocity.

' Provision for removing undesired particles from the drying medium before same reaches the drying units without introducing undue resistance of the current. Y' Provision foi-.efficient low resistance distribul tion of the drying'medium to the points of emission from the drier units.

Provision for eective regulation of the outlets to effect desired concentration of drying medium at points necessary.

Central control for volume of intake to the number ofdrier units used at any time.

Automatic regulation of heat required for the Volume of intake to maintain approximately uniform temperature. l

Automatic regulation ofV velocity of current for each unit used and volume of intake admitted to machine.

Other` objects will appear from the disclosure of the invention.

The invention accordingly comprises the features of construction, combinations of`elements and arrangement of parts which will be exemplied in the construction hereinafterset forth and 'the scope of the application of which will be indicated in the claims. For a fuller understanding of the nature and objects of the'invention, reference should be had to :thefollowing detailed description taken in connection withthe accompanying1drawings: l 1

Fig. 6, aV diagrammatic representation of -an electric heater and controls. Y

Mounted on a base Ill' is a stand which is preferably ared out at the upper extremity and adapted to receive the ilues I2 on each side thereof.. The flues 2 have outlets I3 over which-sleeves III-are rotatably mounted, and preferably exible outlet tubes-I5 are aixed to the sleeves I4 and are adapted to support hoodsV I6. The hoods are preferably double walled with the inner wall |'I perforated and forming a rounded edge with the outer wall so cut Volf at an angle to the hood axis as to comfortably accommodate a human head. 5

In the base I0 are secured a motor I8, a blower I9 driven thereby and `an air heater 2U at the intake end of blower I9 which is preferably of the turbine type with its outlet 2| directed upwardly. The heater 2l] is here shown of the gas 10 type with a control valve 22 disposed near the intake end of blower I9. Air enters base Il) through opening 52 and leaves through 53. The gas llame and air in contact therewith is preferably conned in a chamber 23 open at the bottom 15 but closed at its ends and top. The top plate 24 of chamber 23 is preferably deeply corrugated to provide maximum heating surface and an enclosure 25 approximately of the size of the intake opening to blower I9 is placed over the plate 24 20 to confine the heat above the plate 24 to the air sucked into blower I 9. 'Ihus only air unadultered by the products of combustion is admitted into the hair drier after being heated in passing through the heat chamber 25.

Pivotally mounted on pin 26 and movable along the intake face of blower I9 is a shutter 21, adapted to vary the size of the intake opening 28. The movement of shutter 21 is here effected by means of a rod 29 and moved up or down by means 30 of a lever 30 controlled by a knob 3|. Similarly linked to shutter 2l is a rod 32 which is adapted to open the gas supply valve 22 more and more as the shutter 21 exposes more and more of the intake opening and of course vice versa. These 35 rods are preferably adjustable in length so as to permit variation in the relationship of air intake gas supply to the heater. This adjustment is effected by the threaded ends of rods 29 and 32 moving in tapped pivots 2l and 32 respectively. 40 The velocity of the air driven into the flues I2 is also controllable by the same knob 3| through actuation of a rheostat lever 34, which may be applied to taps 35 of the resistance controlling the speed of the motor to vary same; incidentally 45 the circuit to the motor may be entirely broken at the stop position 3| to shut oif the machine. Thus continuous rotation of knob 3| from its stop point 3|', increases the intake opening, increases the amount of heat supplied and then starts the motor to blow the heated air to the ues l2.

An alternate structure utilizing electric heater units 36 each leading to taps 31 for Varying `the heatgenerated to that required, is shown in Fig. 6.

, This heater replaces the entire gas heater 20 with its chamber 23 and piping connection. The rod 32 is in this construction connected to the Inov-r flue I2 is distributed to the hoods I6 through the f.

respective outlets I3 located along the length of the flues. tioned at each outlet I3 in flues I2 ,to .insure that the. proper fraction of the air 'in the flue is deected into each tube I5 with minimum resistance loss.

The tubes I5 are preferablyfiieinble to permit easy positioning of the hoods I5. Thus an effective distributing arrangement allowing the minimum in resistance loss is provided. i Y

Thehoods I'S'as stated heremabove have perforated inner shells .II through vwhich the heated airis finallyv ejected for-drying the scalp; VIn the preferred construction, a plurality of` Yshutters 42 are slidably mounted between -zthe two walls of the hood and a knobf'fI/Z" on the outsidezof the hood provides the means `for adjustingjthe shutters 42 'to cover va portion of Ithe perforations in shell Il. 'Ihus-When those 'portions of the head 'which have'a light amount of hair had been dried, the current of air directed :atsthoserzportions maybe shut :off by means. of lthe shutters 42,'thereby correspondinglyin'creasingithe drying mediumat the 'other portions of the'fhead Out lets 43 preferablyV extend through Vthe hoodl from ywall to walLto permit the dampened, air to escape after the drying medium had passed .over the lwet hair. This is preferred-to lforcing .all the-rair out from between the :shell I.'Iv and `the persons head. I v

.Simple provisionis made for.nendering"'each drier unit operative or not at will. .This is effected V'by ,mounting :the tubesiflf' on sleeves I4 .over the ue I2 so that the tubes may be oscillated With the sleeves in planes normal'to- .the longitudinal axis 'of the luesv I2. Slots 44 :in flues I2., v'preferably extending =throughan arcof degrees are each adapted to receive a lknobbed zpin 45passing through VVthe sleeve I4, land thereby limit .Y the movement of the sleeve I4 and hence tube vI5 between the position of alignment vofhole I3 .and fthe end of tube I5 and the position oftheirdis'- alignment. In the formerposition theairis .a'dmitted to the hood `It; 'for drying the fhair, 'ingihe latter the air cannot `of course enter the tube I5. At the same time, inthe 'former position Vthe hoodsl 6 is in a position to receive the head, while in the off positionY ythe hood is outof the fway, so that a chair in front of it mayybe utilized .for

other purposes. y

Preferably disposed at the point ofdivision of the air current emerging from` pipe 39 Vandgconvstituting Ythe ylargest section wav'ailable, are vair cleaners 46 for removing all solid particles fromV the air before .same is app-lied to the :hood as `a drying medium'. InV present hair driersgtheldr'ying 'medium contains the dust, the ytiny hair par-Q ticles :floating about in the air as a'result ofthe hair trimming, and otherfunsanitary elements, `and this airis applied to aY freshly shampooed head whose pores are still open because of. lthe heat applied; To overcome'this ,serious defect, `the preferred construction of air filters 46 isa foraminous body of glass wool having a filmiof stand l Ii.

Due to the particular smoothness of the glass and the larger section. at which it is mounted, the air f current passes through in being purified 'with minimum obstruction effect. TheY filters are 5 preferably retained in loop holders 41 secured to the bafde 40, so that renewal of same is readily made after easy removal of the baille from the The heati dissipated the t. baille preferably utiliz/ed to intensify the sterilization of substance limpregnated with a suitable steriliz- 15 fing solution.
